About Stacle
We build synthetic worlds
that rehearse the real one.
Stacle is an AI launch simulation platform. It populates thousands of parallel worlds with multi-agent AI personas — journalists, investors, customers, and skeptics — to predict how a product launch, campaign, or announcement will land before it ships.
Launch simulation for product, marketing, and communications teams
Built for operators
Stacle is designed for teams that have to commit to a launch date and want the objections surfaced while there is still time to answer them.
Calibrated first
Ten live signal sources, distributions instead of point estimates, and agents grounded in real public behaviour.
Company
How Stacle thinks about simulation.
Every decision we make comes back to the same question: does this make the launch decision clearer for the team that has to make it?
Mission
Launch decisions made visible
We believe every team should be able to see how a launch lands before they spend the budget — not after the post is live and the coverage is already written.
What we do
Worlds that argue back
Stacle populates a synthetic world with agents that have their own memory and motives — journalists, investors, customers, skeptics — then runs your launch through thousands of variations of it.
How we build
Calibration before theater
A simulation is only worth acting on if it is anchored in live signal. Grounded priors, honest distributions, and inspectable reasoning matter more than a demo that produces a confident number.
Reach us
Bring us the launch you can't afford to get wrong.
If your team is weighing a positioning change, a pricing move, or an announcement with real downside, that is the right place to start.
We work on the problems that sit between a plan and its reception: how a message reads to an audience that did not write it, which objection travels furthest, how coverage compounds or dies in the first forty-eight hours, and how much of that is signal versus noise.
